Quantum teleportation transfers the quantum state of a system over an arbitrary distance from one location to another through the agency of quantum entanglement. Because quantum teleportation is essential to many aspects of quantum information science, it is important to establish this phenomenon in molecular systems whose structures and properties can be tailored by synthesis. Here, we demonstrate electron spin state teleportation in an ensemble of covalent organic donor–acceptor–stable radical (D–A–R) molecules. Following preparation of a specific electron spin state on R in a magnetic field using a microwave pulse, photoexcitation of A results in the formation of an entangled electron spin pair D•+–A•−. The spontaneous ultrafast chemical reaction D•+–A•−–R → D•+–A–R constitutes the Bell state measurement step necessary to carry out spin state teleportation. Quantum state tomography of the R and D•+ spin states using pulse electron paramagnetic resonance spectroscopy shows that the spin state of R is teleported to D•+ with high fidelity.
